ViewBS error in visualizing BSSeq data

Question

[abseq]

Hi Guys,

I did the analysis of Bisulfite sequencing data. Now I want to visualize the results in ViewBS, but I am getting error in this. I am trying with first two samples as I am getting same error if I use all samples. So I am running below commandline for ViewBS

ViewBS MethCoverage --reference /genome --sample sample1_cov.CX_report.txt.gz,sample1 --sample sample2_cov.CX_report.txt.gz,sample2 --outdir coverage

i am getting error

Use of uninitialized value in multiplication (*) at /ViewBS-0.1.6/lib/Meth/Coverage.pm line 103.
Illegal division by zero at /ViewBS-0.1.6/lib/Meth/Coverage.pm line 103.

I have checked the Coverage.pm file but I couldn't understand it clearly why I am getting this error as I am not a perl expert.

Any help would be highly appreciated. Thanks in advance.
